Controversy had erupted over Delhi police personnel entering Kerala House on October 26 following a complaint that cow meat was being served there.
Kerala Chief Minister Oommen Chandy and his Delhi counterpart Arvind Kejriwal had condemned the "raid". Though Kerala House said cow meat was never on its menu, it stopped serving even buffalo meat for a couple of days.
Delhi Police Commissioner BS Bassi had claimed the canteen was not raided and that the police were merely taking "preventive measures" based on a PCR call. The incident had come close on the heels of lynching of a Muslim man at Bishada village near Dadri in Uttar Pradesh over rumours that he and his family had eaten and store beef.
